Relative Permittivity @ 1 GHz

205°C / 400°F

Continuous Service Temp.

Engineering Balance

High-speed throughput without compromising mechanical toughness.

Balanced Flow Rate

Optimal Processing Window (MFI 24)

High-Velocity Extrusion Stability: Engineered with a balanced Melt Flow Index (22.0–24.0 g/10min), FEP 4622 offers excellent melt delivery for LAN data cable jackets and thin-wall tubing while providing wider thermal processing latitude than ultra-fluid grades.

Stress-Crack Endurance

Superior Flex-Life & Mechanical Toughness

High MIT Flex Endurance: Delivers significantly higher resistance to Environmental Stress Cracking (ESCR) and flex fatigue compared to higher MFI resins. Ensures long-term jacket integrity under continuous vibration and tight bend radii.

Signal Integrity

Lossless Dielectric Barrier

Low Permittivity (2.03 @ 1 GHz): Guarantees minimum signal attenuation and phase distortion for high-frequency plenum cables, Category 6A/7/8 networking wires, and aerospace data conduits with >100 kV/mm dielectric armor.

Extreme Defense

Thermal Stability & Flame Safety

UL 94 V-0 Certified & Chemical Inertness: Features a Limiting Oxygen Index (LOI) >95% with low smoke generation. Completely impervious to harsh solvents, hydraulic fluids, and fuels with continuous service rated to 205 °C (400 °F).

Industry Applications

Engineered for mission-critical connectivity & industrial precision.

APPLICATION 01

High-Speed LAN & Plenum Data Cables

Preferred insulation and jacketing for Cat 6A/7/8 networking lines, high-frequency coaxial cables, and high-density telecom interconnects requiring rigorous flame-retardancy and low transmission loss.

APPLICATION 02

Medical Catheters & Precision Fluid Tubing

Extrudes crystal-clear, ultra-smooth, flexible micro-tubing and medical catheters that demand crack-free bend performance, chemical inertness, and cleanroom bio-compatibility.

APPLICATION 03

Stress-Resistant Micro-Molded Parts

Provides optimal cavity filling for corrosion-resistant valve packings, chemical pump components, and multi-pin electrical connectors subject to continuous mechanical stress.
